Trane- compressor not turning on when calling for AC
 
When the the thermostat in the house calls for cooling the fans turn on but is not blowing cold air. Checked the compressor and it is not turning on. It has power but not turning on. When pressing the middle part of the relay, part# 3100-15Q242, the compressor turns on.

Do I need to replace the relay or am I missing some else that is causing it to not turn on?

Any help would be appreciated.

If the Fan Motor is running the "middle part" (Contactor) is pressed and the Compressor should be running. If not, the compressor has open windings or the thermo switch is open.

If you you can make the fan motor and compressor run only by pressing the contactor, you need to test the contactor coil and check for 24vac on the contactor coil.:mad:
